What is the density of a rock with a volume of 5mL and a mass of 13mL grams

A. 67.5 g/mL
B. 0.37 g/mL
C. 13.5 g/mL
D. 2.7 g/mL

To calculate density, use the formula:

Density = mass/volume

Given that the volume is 5 mL and the mass is 13 grams:
Density = 13 grams / 5 mL

Calculating this expression gives:
Density = 2.6 g/mL

Thus, the correct option is D. 2.7 g/mL.

To calculate the density of the rock, you need to divide the mass of the rock by its volume. In this case, the mass is given as 13 grams and the volume is given as 5 mL.

Density = Mass / Volume

Substituting the given values:

Density = 13 grams / 5 mL

To simplify the units, convert the volume from mL to cm³:

1 mL = 1 cm³

Density = 13 grams / 5 cm³

Simplifying the calculation:

Density = 2.6 grams/cm³

Therefore, the correct answer is D. 2.6 g/mL.
